摘要：

The effects of the concentration of the spreading solution, initial surface concentration of the monolayer, and maximum pressure reached on the compression run, rate of the compression-expansion cycles and number of successive cycles were studied. The influence of the polyethylene oxide length was further studied and showed that the minimum on the π-A isotherms for polystyrene (PS)-PEO disappears in the presence of various amounts of stearic acid. Dynamic light scattering measurements showed aggregation of the block copolymers PS38-PEO90 and PS38-PEO148 in chloroform solutions for the same range of concentrations used in the film balance measurements.
